The styles of non-woven bags can be distinguished from three aspects: shape, pattern and size. The difference in shape mainly lies in the thickness of different parts of the bag and the handle. The overall thickness of the three-dimensional type is relatively large, while the flat type is relatively thin. The bottom organ bag is thick on the bottom and thin on the sides. According to the different handles, it can be divided into hand rope type and rope type. In the pattern, it can be divided into plain color, color, hot flower, silk screen and embroidery. Silk screen printing is a more common method, while embroidery and other patterns are more gorgeous, but the cost is also higher.
